Blue flying fish live in the upper layers of the ocean. Blue flying fish have enlarged pectoral fins that enable them to glide for 4C
meters above the ocean surface and appear to fly.
Which statement best describes how natural selection led to enlarged pectoral fins in blue flying fish?
Oish changed their DNA to express enlarged pectoral fins, changing the allele frequency of the population
Fish were able to live both on land and in the water as a result of their larger pectoral fins
Fish with enlarged pectoral fins were able to glide out of the ocean to escape predators, increasing their fitness
O Fish were able to glide out of the ocean and into other bodies of water to mate with other species
